Brake Fluid: Service Precautions

Use Delco Supreme II Brake Fluid (GM P/N 1052535) or equivalent DOT-3 motor vehicle brake fluid. DOT-5 silicone fluid is not recommended for use in the vehicle's base brake system. DOT-5 brake fluid should never be used.

Brake fluid should always be stored in a closed container. Re-seal brake fluid containers immediately after use. Brake fluid left in an open or improperly sealed container will absorb moisture. This can lower the brake fluid's boiling point and may result in system contamination, corrosion or deterioration of rubber components.
